Description

【０００１】
【発明の属する技術分野】
この発明は１枚、もしくは複数枚の扉をエンジンレールに沿っていずれの向きにも開閉させる自動ドアに関するものである。
【０００２】
【従来の技術及び発明が解決しようとする課題】
１枚、もしくは複数枚の扉を開閉自在に支持した自動ドアではエンジンレールの両側に配置された駆動プーリと従動プーリとの間に巻き掛けられ、駆動プーリと従動プーリとの間で２段等、２列に配置されているベルトの一方である例えば上段と他方である下段のいずれかに各扉がハンガーを介して連結されることにより駆動プーリの回転に伴い、扉の開閉が行われる。
【０００３】
各扉の上端にはエンジンレール上を走行可能にエンジンレールに支持されるハンガーが２箇所に接続され、その内の一方のハンガーがベルトの一方と他方のいずれかに連結されることで、扉はそれが連結された側のベルトの移動の向きに開閉するため、各扉の開放・閉鎖の向きは一義的に定まる。
【０００４】
このため、例えば２枚の扉を有する自動ドアにおいて開口部を通行する対象の規模や通行者数等に応じ、または自動ドアが設置される空間の使用目的等に応じ、いずれか一方の扉のみを開放させる場合と、２枚共開放させる場合を選択的に操作することができない。２枚共開放させる場合でも、２枚の扉を同一向きに開放させる場合と逆向きに開放させる場合を選択的に操作することはできない。
【０００５】
この発明は上記背景より、通行対象の規模や数、空間の条件等に応じて扉の開放パターンを選択できる自動ドアを提案するものである。
【０００６】
【課題を解決するための手段】
本発明では扉をベルトに連結する連結ハンガーを駆動プーリと従動プーリとの間で２段等、２列に配置されているベルトの上段等の一方と下段等の他方のいずれかに選択的に連結可能にすることにより、連結ハンガーのベルトへの連結状態に応じ、駆動プーリの回転に伴い、扉をいずれの向きにも開閉させる。
【０００７】
例えば２枚の扉を有する場合に各扉の連結ハンガーがベルトの一方（例えば上段）か他方（例えば下段）のいずれかに統一されて連結されれば、２枚の扉は同一向きに開放・閉鎖し、一方の扉の連結ハンガーがベルトの一方に連結され、他方の扉の連結ハンガーがベルトの他方に連結されれば、２枚の扉は互いに逆向きに開放・閉鎖する。
【０００８】
従って扉が２枚の場合には連結ハンガーがベルトの一方に連結されるときと他方に連結されるときの２段階に切替え可能であれば、３通りの開放パターンが設定される。
【０００９】
連結ハンガーのベルトへの連結状態の切替えによって複数通りの開放パターンが設定されることで、開口部を通行する荷物その他の対象の規模や通行者数等に応じた使用方法が可能になる。
【００１０】
請求項２に記載のように連結ハンガーをベルトの一方と他方のいずれかに連結される状態と、いずれもにも連結されない中立状態とに３段階に切替え可能にすれば、連結ハンガーを中立状態に置いたときにその連結ハンガーが支持する扉を固定扉として扱い、他の扉のみを開閉させることができるため、扉の前面に仮設の間仕切りが設置される場合等、自動ドアに面する空間の使用目的等に応じた自由な開放パターンを選択することが可能になる。
【００１１】
扉が２枚の場合に、連結ハンガーがベルトの一方に連結されるときと他方に連結されるときに加え、中立状態の３段階に切替え可能である場合にはいずれか一方の扉を固定状態に置ける２通りの開放パターンが加わるため、前記３通りと併せて５通りの開放パターンが設定される。
【００１２】
請求項２の場合に請求項３に記載のように連結ハンガーの、ベルトの一方と他方のいずれかへの連結状態と中立状態を各扉毎に設置される起動センサの検知信号に基づいて制御すれば、自動ドアを通行する対象の規模や通行者数等に応じ、全扉を開放させる操作と少なくともいずれかの１枚の扉のみを開放させる選択的な操作を自動で行うことが可能になる。
【００１３】
請求項２，３の場合、開放させる必要のない扉を固定扉として扱えることで、開放させる扉が全扉の内の一部で済めば、全扉を開放させる場合より扉の開閉に要する動力が小さくて済むため、エネルギの節減が図られる。
【００１４】
【発明の実施の形態】
この発明は図１に示すようにエンジンレール１の両側に配置された駆動プーリ２と従動プーリ３との間に巻き掛けられたベルト４の一方（例えば上段4a）と他方（例えば下段4b）のいずれかに選択的に連結可能な連結ハンガー５に支持された１枚、もしくは複数枚の扉７を駆動プーリ２の回転に伴い、いずれか任意の向きに開閉させる自動ドアである。
【００１５】
図面では駆動プーリ２と従動プーリ３の軸を水平に向けることで、ベルト４を上段4aと下段4bの２段に配列させているが、必ずしも両プーリ２，３の軸を水平に向ける必要はなく、自動ドアの設置条件等に応じて鉛直に向ける、あるいは水平に対して傾斜させる場合もあるため、ベルト４は水平等に２列に配列する場合もある。
【００１６】
図面ではまた、扉７が直線状に開閉する場合を示しているが、エンジンレール１を円弧状に湾曲させ、ベルト４もプーリ等を用いる等によりエンジンレール１に沿って近似的に円弧状に湾曲させて張架することにより扉７を円弧に沿って開閉させ、回転ドアの出入口用の扉として使用することもある。
【００１７】
エンジンレール１と駆動プーリ２及び従動プーリ３は上枠８等の内部に収納され、扉７はその上端に接続される連結ハンガー５とハンガー６の各戸車5a，6aがエンジンレール１上に載り、連結ハンガー５がベルト４に連結されることにより駆動プーリ２の駆動によるベルト４の循環に伴って開閉する。
【００１８】
連結ハンガー５は扉７の上端に接続され、戸車5aを有するハンガー51とハンガー51に取り付けられる連結部材52から構成される。ハンガー51は戸車6aのみを有するハンガー６と同様の形状をする。
【００１９】
図２に示すように連結部材52はハンガー51に固定状態で取り付けられる本体52ａと、本体52ａに例えば昇降自在に支持され、上昇時にベルト４の上段4aに、降下時にベルト４の下段4bに連結状態になる連結材52ｂから構成される。連結材52ｂが昇降する場合、本体52ａには軸52ｃが昇降自在に支持され、(a) に示すように軸52ｃの両端、または(b) に示すようにいずれか一端に連結材52ｂが接続、もしくは形成される。
【００２０】
図２では自動、もしくは手動操作により連結材52ｂをベルト４の上段4aか下段4bに連結する上で、最も単純な機構として連結材52ｂの昇降を利用しているが、本体52ａ等の水平軸回りの回転を利用して連結材52ｂをベルト４の上段4aか下段4bに連結する他、留め具等を用いることで直接的に連結材52ｂをベルト４に連結することも可能である。
【００２１】
図２−(a) は軸52ｃの上下に連結材52ｂ，52ｂを接続することで、単一の連結部材52によってベルト４の上段4aと下段4bのいずれにも連結可能にした場合、(b) はベルト４の上段4a用と下段4b用に２個の連結部材52，52をハンガー51に固定した場合であり、連結材52ｂは上段4a用の連結部材52の軸52ｃの上端と、下段4b用の連結部材52の軸52ｃの下端に接続される。
【００２２】
連結材52、すなわち軸52ｃの昇降はそれに連結されたつまみの昇降や回転等により直接的に直線運動や回転運動を直線運動に変換する機械的手段によって、またはコイルへの通電によって鉄心を往復動させるソレノイドを利用する等、電気エネルギを直線運動に変換する電磁式手段で行われる他、油圧式等、任意の手段で行われる。
【００２３】
電磁式、もしくは油圧式に昇降させる上で、連結部材52に配線や配管を接続する場合、配線や配管はベルト４の循環と連結ハンガー５の移動に追従自在に上枠８の内部に配置されるが、連結ハンガー５や連結部材52に受信機を付属させ、無線で軸52ｃの昇降を行う場合は配線や配管は不要である。
【００２４】
単一の連結部材52がベルト４の上段4a用と下段4b用の連結材52ｂ，52ｂを有する図２−(a) の場合、軸52ｃの昇降は上昇状態と降下状態の２段階に、もしくは上昇状態と中間状態と降下状態の３段階に切替え自在とされる。３段階に切替え自在の場合は請求項２の発明に該当する。
【００２５】
２段階に切替え自在である場合は軸52ｃの上昇時に上端の連結材52ｂがベルト４の上段4aに連結され、降下時に下端の連結材52ｂがベルト４の下段4bに連結される。
【００２６】
図２−(a) 中、二点鎖線は軸52ｃが３段階に切替え自在である場合の中間状態を示すが、軸52ｃの中間状態は連結材52ｂ，52ｂがベルト４の上段4aと下段4bのいずれにも連結されない中立状態となり、その連結ハンガー５が接続された扉７はベルト４の循環に関係なく、閉鎖状態を保ち、固定扉となる。
【００２７】
連結部材52がベルト４の上段4a用と下段4b用に分離している図２−(b) の場合は軸52ｃの昇降が上昇状態と降下状態の２段階に切替え自在とされ、上段4a用の連結部材52の連結材52ｂは上昇時に上段4aに連結され、降下時に上段4aから分離した状態になり、下段4b用の連結部材52の連結材52ｂは降下時に下段4bに連結され、上昇時に下段4bから分離した状態になる。
【００２８】
図２−(b) の場合も連結ハンガー５としては一方の連結部材52の連結材52ｂがベルト４の上段4aに連結されたときに他方の連結部材52の連結材52ｂが下段4bから分離する状態と、一方の連結部材52の連結材52ｂが上段4aから分離したときに他方の連結部材52の連結材52ｂが下段4bに連結される状態の２段階に切替え自在とされる他、一方の連結部材52の連結材52ｂが上段4aから分離したときに他方の連結部材52の連結材52ｂも下段4bから分離する状態の中立状態を含めて３段階に切替え自在とされる。
【００２９】
図２では軸52ｃの昇降によって連結材52ｂのベルト４への連結とベルト４からの分離を行うことから、ベルト４を挟んだ連結材52ｂの反対側には連結材52ｂとベルト４との連結時にベルト４の撓みを防止するためのガイドローラ９が配置される。
【００３０】
図２ではまた、連結材52ｂとベルト４の連結状態のときに循環するベルト４からの力が連結材52ｂに伝達されるよう、連結材52ｂのベルト４側とベルト４の連結材52側を互いに嵌合する歯形状に形成しているが、連結材52ｂとベルト４は軸52ｃが上昇や降下したときに、循環するベルト４の移動と共に連結ハンガー５が移動できるように連結され、逆に軸52ｃが降下や上昇したときに連結材52ｂがベルト４から分離できるように組み合わせられればよく、双方の形状や組み合わせ方は問われない。
【００３１】
図３−(a) 〜(e) は図１に示すように２枚の扉７，７を同一面内に配置した自動ドアにおいて、扉７を開放させるときにベルト４を矢印で示す時計回りに循環させた場合に、各扉７に接続された連結ハンガー５のベルト４の上段4aと下段4bへの連結状態を切り替えた場合毎の扉７の開放パターンの例を示す。
【００３２】
(a) は図１に示すように右側の扉７の連結ハンガー５を上段4aに連結し、左側の扉７の連結ハンガー７を下段4bに連結したときの様子を示す。この場合は両扉７，７が引分け戸式に互いに逆向きに開放する。
【００３３】
(b) は右側の扉７の連結ハンガー５を中立状態にし、左側の扉７の連結ハンガー５を下段4bに連結したときの様子を示す。この場合は右側の扉７が固定状態に保たれ、左側の扉７のみが片引き戸式に開放する。
【００３４】
(c) は右側の扉７の連結ハンガー５を上段4aに連結し、左側の扉７の連結ハンガー５を中立状態にしたときの様子を示す。この場合は(b) と逆に、左側の扉７が固定状態に保たれ、右側の扉７のみが片引き戸式に開放する。
【００３５】
(d) は両扉７，７の連結ハンガー５，５を共に下段4bに連結したときの様子を、(e) は両連結ハンガー５，５を共に上段4aに連結したときの様子を示す。これらの場合は２枚の扉７，７が連なった状態で同一向きに開放する。
【００３６】
図１は２枚の扉７，７を引分け状態に配置した場合であるが、２枚の扉７，７を引違い状態に配置すれば、扉７の開放状態で両扉７，７を重ねることができるため、図３に示す例より多くの開放パターンを設定することができる。
【００３７】
図４に示すように３枚以上の扉７を同一面内に配置した場合には例えば最も右側の扉７の連結ハンガー５をベルト４の上段4aに連結し、その扉７を右側へ開放させる場合のみに関して図５−(a) 〜(f) に示すように６通りの開放パターンが想定されるため、各扉７の連結ハンガー５のベルト４への連結状態を切り替えることで、２枚の場合より多くの開放パターンを設定することができる。
【００３８】
図５−(a) は中間の扉７と左側の扉７の両連結ハンガー５，５をベルト４の上段4aに連結し、３枚共右側へ開放させる場合、(b) は中間の扉７の連結ハンガー５をベルト４の上段4aに、左側の扉７の連結ハンガー５を下段4bにそれぞれ連結し、中間の扉７を右側へ、左側の扉７を左側へ開放させる場合、(c) は中間の扉７と左側の扉７の両連結ハンガー５，５をベルト４の下段4bに連結し、中間の扉７と左側の扉７を左側へ開放させる場合である。
【００３９】
(d) は中間の扉７の連結ハンガー５をベルト４の上段4aに連結し、左側の扉７の連結ハンガー５を中立状態にし、中間の扉７を右側へ開放させ、左側の扉７を固定状態にする場合、(e) は中間の扉７の連結ハンガー５を中立状態にし、左側の扉７の連結ハンガー５を下段4aに連結し、中間の扉７を固定状態にしながら、左側の扉７を左側へ開放させる場合、(f) は中間の扉７と左側の扉７の両連結ハンガー５，５を中立状態にし、中間の扉７と左側の扉７を固定状態にする場合である。
【００４０】
図６は２枚の扉７，７を引分け状態に配置した場合に、各扉７毎に起動センサ10を設置し、通行対象の規模や数に応じ、各扉７の連結ハンガー５の連結材52ｂを起動センサ10の検知信号に基づいて制御し、図３−(a) 〜(e) に示す開閉パターンを自動で操作する請求項３の発明の実施例を示す。
【００４１】
各扉７の起動センサ10は扉７の全幅の範囲内にある物体を検知し、通行対象がいずれか一方の扉７の範囲内に納まり、その側の起動センサ10のみが物体を検知したときにその側の扉７のみが開閉する。物体が両起動センサ10，10に検知されたときは両扉７，７が開閉する。図６中、一点鎖線が上枠８に設置された起動センサ10が検知し得るエリアを示す。
【００４２】
起動センサ10の検知信号はコントローラへ送られ、コントローラの指令に基づいて各連結ハンガー５の連結材52ｂの昇降等によるベルト４への連結とベルト４からの分離の切替え状態が制御される一方、駆動プーリ２が駆動し、扉７，７の開閉が制御される。
【００４３】
両起動センサ10，10が物体を検知したときは図３−(a) に示すように右側の扉７の連結ハンガー５が上段4aに連結され、左側の扉７の連結ハンガー７が下段4bに連結されることにより両扉７，７が開放する。両起動センサ10，10が物体を検知したときには両扉７，７の連結ハンガー５，５を共に上段4aに連結する、あるいは下段4bに連結することにより図３−(d) ，(e) に示すように両扉７，７を同一向きに開放させることもできる。
【００４４】
一方の起動センサ10が物体を検知し、他方の起動センサ10が検知しないときは図３−(b) ，(c) に示すように検知した側の扉７の連結ハンガー５が下段4b、もしくは上段4aに連結され、検知しない側の扉７の連結ハンガー５が中立状態に保たれることにより一方の扉７が開放する。
【００４５】
起動センサ10には図示するように扉７上の上枠８に設置される光線スイッチや床面に設置されるマットスイッチ等が使用される。
【００４６】

BACKGROUND OF THE INVENTION
The present invention relates to an automatic door that opens and closes one or more doors in any direction along an engine rail.
[0002]
[Prior art and problems to be solved by the invention]
In an automatic door that supports one or more doors so that they can be opened and closed, the automatic door is wound between a driving pulley and a driven pulley arranged on both sides of the engine rail, and two steps between the driving pulley and the driven pulley. Each door is connected to one of the belts arranged in two rows, for example, either the upper stage or the other lower stage via a hanger, whereby the door is opened and closed as the drive pulley rotates.
[0003]
The top of each door is connected to two hangers supported on the engine rail so that it can run on the engine rail, and one of the hangers is connected to one of the belts and the other, so that the door Opens and closes in the direction of movement of the belt on the side to which it is connected, so that the opening / closing direction of each door is uniquely determined.
[0004]
For this reason, for example, only one of the doors depends on the size of the target passing through the opening in the automatic door having two doors, the number of passers, or the purpose of use of the space where the automatic door is installed. It is not possible to selectively operate the case of opening and the case of opening both. Even when the two doors are opened, it is not possible to selectively operate the case where the two doors are opened in the same direction and the case where the doors are opened in the opposite direction.
[0005]
The present invention proposes an automatic door capable of selecting a door opening pattern according to the scale and number of traffic objects, space conditions, and the like.
[0006]
[Means for Solving the Problems]
In the present invention, the connecting hanger for connecting the door to the belt is selectively set to either one of the two stages such as the upper stage of the belt arranged in two rows between the driving pulley and the driven pulley and the other of the lower stage. By enabling the connection, the door is opened and closed in any direction as the drive pulley rotates according to the connection state of the connection hanger to the belt.
[0007]
For example, if you have two doors, if the connecting hangers for each door are connected to one of the belts (for example, the top) or the other (for example, the bottom) and connected together, the two doors will open in the same direction. When the door is closed and the connecting hanger of one door is connected to one of the belts and the connecting hanger of the other door is connected to the other of the belts, the two doors open and close in opposite directions.
[0008]
Therefore, in the case of two doors, if the connection hanger can be switched to two stages when it is connected to one of the belts and the other, three opening patterns are set.
[0009]
By setting a plurality of opening patterns by switching the connecting state of the connecting hanger to the belt, a usage method according to the size of the baggage and other objects passing through the opening and the number of passersby becomes possible.
[0010]
If the connection hanger can be switched in three stages between a state in which the connection hanger is connected to one or the other of the belt and a neutral state in which neither is connected to the belt, the connection hanger is in a neutral state. Because the door supported by the connecting hanger when placed on the door can be treated as a fixed door and only other doors can be opened and closed, the space facing the automatic door, such as when a temporary partition is installed on the front of the door It is possible to select a free opening pattern according to the purpose of use.
[0011]
When there are two doors, when the connecting hanger is connected to one of the belts and the other, it is possible to switch to one of the three neutral states. Since two kinds of opening patterns that can be placed in the area are added, five kinds of opening patterns are set together with the above three kinds.
[0012]
In the case of claim 2, as in claim 3, the connection state of the connection hanger to one of the belt and the other and the neutral state are controlled based on the detection signal of the start sensor installed for each door. In this way, it is possible to automatically perform an operation to open all the doors and a selective operation to open at least one of the doors depending on the scale of the object passing through the automatic door, the number of passers, etc. Become.
[0013]
In the case of Claims 2 and 3, if a door that does not need to be opened can be handled as a fixed door, and if the door to be opened is a part of all the doors, the power required to open and close the doors than when all the doors are opened Can save energy.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, as shown in FIG. 1, one (for example, upper stage 4a) and the other (for example, lower stage 4b) of a belt 4 wound between a drive pulley 2 and a driven pulley 3 disposed on both sides of an engine rail 1 are provided. This is an automatic door that opens or closes one or a plurality of doors 7 supported by a connecting hanger 5 that can be selectively connected to any one of them in accordance with the rotation of the drive pulley 2.
[0015]
In the drawing, the belt 4 is arranged in two stages, an upper stage 4a and a lower stage 4b, by horizontally orienting the axes of the driving pulley 2 and the driven pulley 3, but it is not always necessary to orient the axes of the pulleys 2 and 3 horizontally. In some cases, the belt 4 may be oriented vertically or inclined with respect to the horizontal depending on the installation conditions of the automatic door, and therefore the belt 4 may be arranged in two rows horizontally.
[0016]
The drawing also shows the case where the door 7 opens and closes linearly, but the engine rail 1 is curved in an arc shape, and the belt 4 is also approximately arc-shaped along the engine rail 1 by using a pulley or the like. The door 7 may be opened and closed along a circular arc by being bent and stretched, and may be used as an entrance / exit door for the revolving door.
[0017]
The engine rail 1, the driving pulley 2 and the driven pulley 3 are housed in an upper frame 8 or the like, and the door 7 has a connecting hanger 5 connected to its upper end and each door 5a, 6a of the hanger 6 placed on the engine rail 1. When the connecting hanger 5 is connected to the belt 4, the connecting hanger 5 opens and closes as the belt 4 is circulated by driving the driving pulley 2.
[0018]
The connecting hanger 5 is connected to the upper end of the door 7 and includes a hanger 51 having a door 5a and a connecting member 52 attached to the hanger 51. The hanger 51 has the same shape as the hanger 6 having only the door wheel 6a.
[0019]
As shown in FIG. 2, the connecting member 52 is fixed to the hanger 51 in a fixed state, and is supported by the main body 52a so as to be movable up and down, for example, and connected to the upper stage 4a of the belt 4 when ascending and to the lower stage 4b of the belt 4 when descending. It is comprised from the connection material 52b which becomes a state. When the connecting member 52b moves up and down, the shaft 52c is supported by the main body 52a so as to be able to move up and down, and the connecting member 52b is connected to either end of the shaft 52c as shown in (a) or to one end as shown in (b). Or formed.
[0020]
In FIG. 2, when the connecting member 52b is connected to the upper stage 4a or the lower stage 4b of the belt 4 automatically or manually, raising and lowering of the connecting member 52b is used as the simplest mechanism. In addition to connecting the connecting member 52b to the upper stage 4a or the lower stage 4b of the belt 4 by using the rotation around, it is also possible to connect the connecting member 52b directly to the belt 4 by using a fastener or the like.
[0021]
FIG. 2 (a) shows a case where the connecting members 52b and 52b are connected to the upper and lower sides of the shaft 52c so that the single connecting member 52 can be connected to either the upper stage 4a or the lower stage 4b of the belt 4. ) Is a case where the two connecting members 52, 52 are fixed to the hanger 51 for the upper stage 4a and the lower stage 4b of the belt 4, and the connecting member 52b includes the upper end of the shaft 52c of the connecting member 52 for the upper stage 4a and the lower stage. It is connected to the lower end of the shaft 52c of the connecting member 52 for 4b.
[0022]
The connecting member 52, that is, the shaft 52c is moved up and down by mechanical means for directly converting linear motion or rotational motion into linear motion by lifting or rotating a knob connected thereto, or by energizing the coil. This is performed by an electromagnetic means that converts electric energy into linear motion, such as by using a solenoid to be used, or by any means such as a hydraulic type.
[0023]
When wiring or piping is connected to the connecting member 52 for raising or lowering electromagnetically or hydraulically, the wiring or piping is arranged inside the upper frame 8 so as to follow the circulation of the belt 4 and the movement of the connecting hanger 5. However, when the receiver is attached to the connection hanger 5 or the connection member 52 and the shaft 52c is moved up and down wirelessly, wiring and piping are not necessary.
[0024]
In the case of FIG. 2- (a) in which the single connecting member 52 has the connecting members 52b and 52b for the upper stage 4a and the lower stage 4b of the belt 4, the shaft 52c is moved up and down in two stages, an up state and a down state, or It is possible to switch between three stages of an ascending state, an intermediate state, and a descending state. The case where it can be switched in three stages corresponds to the invention of claim 2.
[0025]
When switching between two stages is possible, the upper connecting member 52b is connected to the upper stage 4a of the belt 4 when the shaft 52c is raised, and the lower connecting part 52b is connected to the lower stage 4b of the belt 4 when lowered.
[0026]
